A.2.78 –Qoption phase option[,option…]

Passes option to the compilation phase.

To pass multiple options, specify them in order as a comma-separated list. Options that are passed to components with -Q can be reordered. Options that the driver recognizes are kept in the correct order. Do not use -Q for options that the driver already recognizes. For example, the C++ compiler recognizes the -z option for the linker (ld). If you issue a command like this

     CC -G -zallextract mylib.a -zdefaultextract ... // correct

the -z options are passed in order to the linker. But if you specify the command like this

     CC -G -Qoption ld -zallextract mylib.a -Qoption ld -zdefaultextract ... // error

the -z options can be reordered, giving incorrect results.

A.2.78.1 Values

phase must have one of the following values.

Examples

In the following command line, when ld is invoked by the CC driver, –Qoption passes the –i and –m options to ld.

example% CC -Qoption ld -i,-m test.c

Warnings

Be careful to avoid unintended effects. For example,

-Qoption ccfe -features=bool,iddollar

is interpreted as

-Qoption ccfe -features=bool -Qoption ccfe iddollar

The correct usage is

-Qoption ccfe -features=bool,-features=iddollar
